Technical report: use of ultrasound guidance in the removal of tunnelled venous access catheter cuffs.

Venous access catheters are employed for a wide variety of reasons. On removal of the catheter, the subcutaneous catheter cuff can be difficult to extract; retention of the cuff has recognized complications. We describe a simple ultrasound technique that assists in the identification of the cuff within the subcutaneous tissues, simplifying subsequent cuff removal. This may lead to a reduction in associated complications.
